No Charger to Charge included

I bought 2 of these at Sam's in Cape Coral, FL. One to leave in Florida and One to bring to NY for summer use. I got here last week and realized this unit does not have the Charger to charge the jump pack. Basically useless without one. How do I get one?

Older model was a much better design

This newer model operating position is flat. The air hose is shorter so if your valve stem is at the top you have to hold it up to get your tire aired up. It doesn't fit down in my side box like the older model I have. The light is built into the lid of the air hose cover so you can't aim it as well. It comes with a charge adapter that you have to keep somewhere. There's nowhere on the unit to store it. If you lose the cable you can't charge it and it's junk. On the older model you could plug an extension cord right into the back and charge it.

Purchase in December 2025, and the airpump no longer works as of Aug 28th. I have also used it to jump start my antique truck. It would not work unless the tool is fully charged. I find the station too heavy and the jump start cables too short as well. Luckily, Sam's return policy allows me to take it back.

All in one

I started traveling and driving out of town now. Love having this in my car and know I can jump start my car or air up a low tire without anything or anyone else. Thankfully, haven't needed it for that yet. We did air up a bike tire, and it worked well and fast. The light is super bright as well!

Disappointing.

We have to return this. The air compressor is not functioning.

Multifunctional Portable Compressor & Jump Starter

Seems to be a great product. It's a brand new item for me. Much better than the corded compressors I have used in the past.

Better than jumper cables.

Excellent device to use to jump start a weak battery engine or pump up low tires. With newer cars it can be risky to use standard jumper cables when your car has so many digital chips that can be damaged if something goes wrong.

There are others to consider

It lasted well for about three years, limped along for another three, now is so weak it won't turn over a lawn mower starter. I'm looking to replace it with a compact one from another manufacturer.

Convenient but short longevity

[This review was collected as part of a promotion.] The Stanley PPS12CF was convienent to have around for the bit of time I had it. I kept it fully charged in my trunk. The air compressor function worked well, and the jump starter came in handy. The Stanley PPS12CF is very easy to use and comes with very clear instructions. Unfortunately, the battery life was disappointing-it took a long time to charge and drained quickly. After only three months of normal use it completely stopped working. It was useful while it lasted. If it wasn't for the lack of durability and battery performance it would've been extremely reliable.
